Here is some simple instructions for running Left-Right Twin Higgs model at 
CalcHEP.  Please contact authors if you have any questions or need some help.

1. Unpack model code and put it in calchep models/
2. Launch calchep and load model files
3. Have fun

Additional useful hints:
1. Most relevant model paramters are 
f1, f2, MMp, 
MZH, MWH, MtH, Mh1, Mh2, MAx, MhR, and MH. 
if you want to run other parameter choices instead of the default one, 
use para.data and mass.data.  Notice that all those parameters are correlated 
and need to be changed together.

2. use CalcHEP batch mode to save your time typing the input parameters, 
and also make automated running of CalcHEP.  See sample batch file "pairtH", 
which shows how to set the model parameters and how to run all the subprocesses
together and automatically sum the cross sections of subprocesses.  Read
CalcHEP manuel for more instructions on batch mode running.
